Abstract

A common assumption in the analysis and modelling of co-channel interference (CCI) is the circular shape of the cells. However, despite its simplicity, this approach has certain drawbacks. In this paper, we propose an alternative approximate method which considers hexagonal-shaped cells. We develop a geometrical-based stochastic model and derive analytical expressions for the statistics of the angle-of-arrival of the uplink interfering signals in a cellular system. Simulations performed exhibit the characteristics of our proposal and evaluate both hexagonal and circular approximations. The impact of various parameters on the performance of a cellular system is also investigated. The derived expressions simplify the analysis of wireless networks and improve the accuracy of the simulations when hexagonal cells are employed.
